BACKGROUND INFORMATION 1. Technical Field

In the concrete building industry, it is necessary to regularly cleanconcrete tools of the concrete materials that build up on the tools toprevent the concrete from hardening and ruining the tool. Such concretetools include wheelbarrows, rubber boots, work boots, gloves, safetyglasses, levels, tape measures, shovels, rakes, concrete rakes,come-along rakes, tampers, screeds, straight edges, bump cutters, flatpieces of lumber, bull floats, magnesium floats, kneeling boards,trowels, float blades, troweling blades, groove cutters, jointers,edgers, and brooms. All of these different tools and devices need to bekept as free of concrete material as possible. Concrete finishing toolsespecially need to be kept free of hardened concrete material in orderto maintain smooth edges and surfaces necessary to produce a smoothconcrete surface with minimal surface irregularities, such as scratches,bumps, ridges, and grooves.

2. Background Art

This section is for informational purposes only and does not necessarilyadmit that any publications discussed or referred to herein, if any, areprior art.

In the concrete building industry, wheelbarrows are used extensively.These wheelbarrows usually have a metal tray made of steel or similarstrong metal. The tray has a generally flat bottom and side surfacesthat extend upwardly at an angle to form a basin or dish-like structurefor holding things. For ease of understanding, since the term “tray”generally refers to flat structures or plates, such as used in foodservice, and since the wheelbarrow often can be relatively and more likea basin in shape, the term “basin” will be used herein to refer to thetray of the wheelbarrow. The basin is mounted on a support frame, alsousually made of a strong metal. Connected to the support frame are twoextending handles made of wood or metal. Finally, one or sometimes twowheels are connected to the frame to both support the wheelbarrow andpermit a worker to roll the wheelbarrow from one location to the other.Wheelbarrows for concrete work usually must be made of quite durablematerials due to the weight of the concrete mix that is oftentransported in the wheelbarrows.

Wheelbarrows are traditionally used in the concrete building industryfor a few main functions. The first is transporting items from onelocation to the other, such as concrete tools and concrete materials,such as water, aggregate (rock, sand, or gravel), and Portland cement. Asecond function is for mixing batches of concrete in the basin. A thirdfunction is for holding water in the basin and then using the basin as asort of wash basin for cleaning concrete materials off of the concretetools.

When using the wheelbarrow basin as a wash basin, the wheelbarrow basinis at least partially filled with water. A worker then uses brushes andscrapers to remove the concrete material from the tools. Some of thetools, such as trowels, have handles that allow for the tool to be hungon the side of the wheelbarrow basin while cleaning. Larger items, likethe lengthy concrete screeds, push brooms, and rakes can be leanedagainst the wheelbarrow, but are quite difficult to handle. Often thesetools, especially brooms and similar devices, are simply soaked withwater and then struck against the ground to shake off the concretematerial, leaving substantial amounts of concrete material on the groundof the work site, which is undesirable. Most tools though are left in anearby bucket or simply dropped into the water in the wheelbarrow basinlike dishes in a kitchen sink.

The cleaning process is both time-consuming and labor-intensive. Forexample, a worker cleaning such tools cannot easily place them somewhereduring cleaning or drying. Leaving the tools in a bucket requires theworker to regularly bend down and up to pick up and deposit tools, whichis often quite painful and strenuous for a concrete worker at the end ofa long work day. Often tools get dropped or knocked off of the edge ofthe wheelbarrow during cleaning, thereby possibly dirtying the toolsagain and requiring the worker to once again bend down and up. Thecleaning process requires the worker to use two hands: one to hold abrush and one to hold the tool. While this is not very challenging forsmall, handheld tools, it is quite cumbersome and difficult for largetools like screeds and brooms that are hard to manipulate with one hand.Tools and brushes often are dropped into the water, again riskingbecoming dirty due to concrete materials in the dirty water. Inaddition, as the water becomes increasingly dirtied with concretematerials, it can become more and more opaque, thereby making itdifficult for the worker to see where the tool or brush is in the water.

The fact that the tools and brushes fall into the water and sometimescannot be readily seen is one of the biggest problems facing a concreteworker during the cleaning process, especially in colder climates orconditions. For example, if a worker is working in colder conditions,such as about 4-16° C. (39.2-60.8° F.) or colder, the water in thewheelbarrow is similarly as cold. As the worker cleans the tools at theend of a long work day—at which point the worker is usually quite tiredand the worker has less strength in his body and hands—the worker mustregularly immerse his hands in the water. The cold water causes theworker's hands to become quite cold and possibly numb, depending on thesurrounding temperature, making it very difficult if not near impossibleto readily grip and hold the tools and cleaning brushes. This causes theworker to drop the tools and brushes more often, thereby lengthening thecleaning process. The worker cannot grip the tools and brushes asfirmly, thereby rendering the cleaning less effective. The worker mustbend over more often to pick up dropped tools and brushes, which is onlymade more challenging by stiff muscles caused by the cold weather. Theworker may even tend to try to take shortcuts or work faster to get thejob finished due to pain and fatigue, thereby risking damaging the toolsand/or not cleaning them sufficiently or properly. There is currently nosolution available on the market to concrete workers to address theseproblems of which the inventor is aware.

BRIEF SUMMARY

In order to address the above problems of cleaning concrete tools, aconcrete tool support shelf or rack for a concrete wheelbarrow orsimilar device, as well as a method of using a concrete tool supportshelf or rack to clean concrete materials from concrete tools, aredisclosed herein in one or more exemplary embodiments.

In accordance with at least one possible exemplary embodiment, a shelfis designed to be installed on a wheelbarrow. It should be noted thatthe term “shelf” should be understood as encompassing any shelf orshelf-like structures, such as racks, trays, tables, grates, plates, orsimilar structures that have a relatively wide and/or long supportsurface and a smaller height or thickness. It should also be noted thatthe term “wheelbarrow” refers to any wheelbarrow or wheelbarrow-likedevice that includes a basin.

The shelf is designed to be seated on or connected to or attached to ordisposed at, either temporarily, removably, or permanently, a portion ofan edge or lip of a basin of a wheelbarrow in the manner of a partialcover or lid over or across a portion of the basin. During a concretetool cleaning or washing process, concrete tools and cleaning devicescan be placed on or suspended from or connected to the shelf. In thismanner, the concrete tools and cleaning devices can be convenientlystored out of the water in the basin, minimizing the above problemsrelating to the current cleaning methods. In addition, in accordancewith at least one possible exemplary embodiment, the shelf could havecleaning devices or structures or other concrete tool treatment devicesor structures connected or attached to the shelf in a permanent orremovable manner, or such devices or structures could be formedintegrally as part of the shelf itself, in order to free up the hands ofthe worker for more efficient and easier cleaning of concrete tools. Theshelf has openings therein to permit flow of liquids, such as water orcleaning solution, and solids, such as concrete material and dirt,through the shelf and into the wheelbarrow basin underneath the shelf topromote drying and minimize accumulation of solid materials on theconcrete tools and the shelf itself. In accordance with at least onepossible exemplary embodiment, the shelf has a retaining flange orbracket or similar connecting or retaining or holding structure topermit the shelf to be removably mounted or suspended from a portion ofthe lip or edge of the basin of the wheelbarrow when the shelf is not inuse, such that the shelf is easily transported on or with thewheelbarrow but the basin is completely open and not obstructed by theshelf.

The shelf may be constructed from any number of materials that aresubstantially water-resistant, durable, and rigid, such as steel,aluminum, other metals, wood, hard plastic, hard rubber, or hardelastomers, and could include a protective coating thereon to increasewater resistance and durability. The openings in the shelf could beachieved by the inclusion of slots or holes in the main body of theshelf, or by designing the main body of the shelf in a grid or mesh orwire frame design.

DETAILED DESCRIPTION

FIG. 1 shows a wheelbarrow and concrete tools for use in the concretebuilding and construction industry. The wheelbarrow is the type ofwheelbarrow suitable for use in the concrete building industry, whichare often heavier duty wheelbarrows made of steel or similar metals.Different concrete tools are also shown, such as rubber boots, workboots, gloves, safety glasses, shovels, rakes, concrete rakes,come-along rakes, screeds, straight edges, bump cutters, flat pieces oflumber, kneeling boards, trowels, float blades, troweling blades, groovecutters, jointers, edgers, and brooms. In addition, cleaning brushes andsimilar devices are also shown.

FIG. 2 shows the wheelbarrow with a shelf in accordance with at leastone possible exemplary embodiment. Various concrete tools are positionedon the shelf.

FIG. 3 shows the shelf 5 installed on the wheelbarrow 1. In theembodiment shown, the shelf 5 has a contoured design to substantiallyfollow the shape of a portion of the edge or lip of a basin, i.e., atray, 3 of the wheelbarrow 1. The basin 3 is the basin-shaped structurethat is used to carry materials or objects therein. The shelf 5 has amain body or support portion 7 that, upon installation on a wheelbarrow,is disposed to cover over or span across a portion of the basin 3. Inthe exemplary embodiment shown, the main body portion 7 of the shelf 5is the form of a wire-frame grate. This design permits water andconcrete material to pass through the shelf 5 and into the basin 3during cleaning of concrete tools. In addition, items such as brushes orbrooms can be rubbed against the grating in order to scrape off concretematerial.

The shelf 5 has an outer flange or edge 9 that extends transverse to oressentially perpendicular to the upper surface of the shelf 5. The outerflange 9 acts as a retaining structure to minimize or prevent slidingmovement of the shelf 5 along the lip of the basin 3 of the wheelbarrow1. The outer flange 9 also can retain the shelf 5 in the installed oruse position when the wheelbarrow 1 is tipped or inclined up to 90degrees, such that the wheelbarrow 1 can be tipped and emptied as neededwithout the shelf 5 falling off of the basin 3. The shelf 5 also has aninner flange or edge 11 that extends transverse to or essentiallyperpendicular to the lower surface of the shelf 5. The inner flange 11is also contoured but acts against the inside of the lip of the basin 3.Similarly to the outer flange 9, the inner flange 11 minimizes orprevents sliding movement of the shelf 5. Both the outer flange 9 andthe inner flange 11 can be formed as a single flange structure or can beformed as multiple flange sections that are spaced apart. In theembodiment shown in FIG. 3 , the outer flange 9 is a single structureextending from one end of the shelf to the other, whereas there are twoinner flanges 11 that are substantially shorter and disposed on oppositeends of the shelf. The inner flanges 11 can be seen more readily in theviews of the lower side of the shelf, such as in FIG. 9 , for example.

The shelf 5 includes a scraping flange 13 that can be used to cleanconcrete tools, as will be discussed herein below. The shelf 5 alsoincludes a retaining bracket 15 that is used to suspend the shelf 5 fromthe lip of the basin 3 in a storage position when the shelf 5 is not inuse. An optional brush 17 is connected to the shelf 5, either in apermanent or removable manner, such as by bolts or screws or similar.The brush 17 is thereby held in place on the shelf 5, such that a workercan rub concrete tools against the brush 17 to clean the concrete tools.This design allows the worker to hold the concrete tool with both hands,rather than holding the concrete tool in one hand and the brush 17 inthe other, which is advantageous in cold weather and/or when trying toclean a larger tool, such as a broom or a screed. This design alsoallows the worker to use more force with both hands to remove concretematerial that is sticking to the concrete tool. While only one brush 17is shown in FIG. 3 , more than one brush can be connected to the shelf5, which brushes can be of different configurations, such as adouble-brush device, or of different materials, such as wire brushes.Finally, by connecting the brush 17 to the shelf 5, the brush 17 willnot fall into the water accidentally. All of these advantages greatlyincrease the ease and efficiency of cleaning the concrete tools.

The shelf 5 also includes holding rings 19. The shelf 5 in FIG. 3 onlyhas two holding rings 19, but more holding rings 19 could be added. Theholding rings 19 are integral to the metal shelf 5. They are used tohold brushes or similar cleaning implements that have a handle andcleaning head, wherein the handle is inserted through the holding ring19 and the cleaning head rests against the holding ring 19 such that thecleaning implement is suspended from the holding ring 19. The holdingring 19 makes it very easy for a worker to store the cleaningimplements, usually handheld brushes, during the cleaning process,rather than the cleaning implements being left on the ground, in abucket, or in the water in the basin 3.

FIGS. 4, 5, 6, and 7 show views of the upper side of the shelf 5. FIG. 4shows a length dimension of a front edge of the shelf 5 of approximately26 inches. FIG. 5 shows a width dimension from the front edge to a backedge of approximately eight inches. FIG. 6 shows another width dimensionfrom the front edge to an edge of a holding ring 19 of approximatelynine inches. FIG. 7 shows a diagonal dimension from a corner of theshelf 5 to the opposing holding ring 19 of approximately 26 inches. Itshould be noted at this time that all measurements disclosed herein arefor exemplary purposes in accordance with at least one possibleexemplary embodiment, and that all reasonable variations understandableto the person of ordinary skill in the art are disclosed herein. Inaddition, the shelf 5 is designed to fit with most any wheelbarrowsuitable for use in the concrete building and construction industry, butcould easily be modified as necessary to fit essentially anywheelbarrow.

FIGS. 8, 9, 10, 11, and 12 show views of the lower side of the shelf.FIGS. 8 and 10 show a length dimension of approximately 26 inches. FIG.9 shows the retaining bracket 15, which has a width dimension ofapproximately three inches. FIGS. 11 and 12 show views of the lowersurface of the shelf 5, wherein bolts and washers used to clamp or holdthe brush 17 to the shelf 5 are shown. FIG. 13 shows a view of the upperside of the shelf 5 and the brush 17 connected thereto. FIGS. 14 and 15show additional views of the lower side of the shelf 5, wherein theright-angle or L-shaped design of the retaining bracket 15 can be easilyseen. FIG. 16 shows the shelf 5 installed on the wheelbarrow 1, whereasFIG. 17 shows the shelf pivoted off of the wheelbarrow 1.

FIGS. 18, 19, and 20 show the shelf hanging off the lip of the basin ofthe wheelbarrow in a storage position when not in use. The retainingbracket 15 allows the shelf 5 to be hung from the edge of the basin 3 ina position adjacent the handles of the wheelbarrow 1. In this exemplaryembodiment, the width of the shelf 5 is such that the shelf 5 does notcontact or only slightly contacts the handles of the wheelbarrow 1. Thisdesign permits the worker to easily carry the shelf 5 on the wheelbarrow1 to any location without interfering with or blocking access to theentirety of the basin 3.

FIGS. 21, 22, and 23 show the steps of moving the shelf out of thestorage position and into the use position above the basin of thewheelbarrow. The shelf 5 is first grasped and lifted upwardly out of theuse position. The shelf 5 is then easily pivoted and over the lip of thebasin 3, as shown in FIG. 22 , and then placed into the use position, asshown in FIG. 23 .

FIGS. 24 and 25 show the wheelbarrow in an inclined position with theshelf being retained in the use position by the outer flange 9. Thewheelbarrow 1 can be pivoted up to 90 degrees before the shelf 5 wouldfall off. In accordance with at least one possible exemplary embodiment,the shelf 5 and/or the outer flange 9 could include an additionalretaining piece or structure that could retain the shelf 5 in place evenif the wheelbarrow 1 were pivoted past 90 degrees.

FIGS. 26 and 27 show a double-brush device for use in cleaning concretetools that can be connected or attached to the shelf. FIGS. 28 and 29show a single-brush device for use in cleaning concrete tools that isconnected or attached to the shelf. As can be seen, a concrete trowelcan be easily and quickly cleaned by rubbing the trowel against thebrushes.

FIGS. 30, 31, and 32 show a concrete tool being scraped against an edgeof the shelf. As is well known in the concrete building industry,concrete tools for smoothing and edging require a smooth anduninterrupted edge to achieve a smooth finish of the concrete. However,it is common for concrete tool edges to become chipped or damaged. Inaccordance with at least one possible exemplary embodiment, the side ofthe shelf 5 includes a metal file structure to permit filing of an edgeof a concrete tool. As shown in FIGS. 30, 31, and 32 , a worker couldfile the tool by scraping the tool up and down or back and forth acrossthe file. By including the file on the shelf, not only is the filereadily available to the worker at the work site, but the file is alsoheld firmly in place to allow a vigorous scraping or filing to achievethe best results with minimal effort.

FIGS. 33, 34, 35, 36, and 37 show steps in cleaning a concrete screedwith the shelf. As is known in the industry, concrete screeds are verylong bars of wood or metal, and thus are unwieldy and can be difficultto clean. A shown in FIGS. 33 and 34 , the shelf 5 provides a stablesupport surface on which to place the screed during cleaning. Inaddition, the scraping flange 13 can be used to very quickly scrapeconcrete material off of the screed. As shown in FIGS. 35, 36, and 37 ,all a worker has to do is slide the screed back and forth along thescraping flange 13. Not only does this quickly clean the screed, but itallows the worker to use two hands to move the screed around and applymore force to remove concrete material that might be more stronglyadhered to the screed. In addition, since the shelf 5 is positionedabove the basin 3, the concrete material scraped off the screed iscollected in the basin 3, rather than being left on the ground of thework site to create a messy or unclean appearance.

Another use of the scraper flange 13 is for opening concrete bags duringconcrete work. Bags of concrete mix are fairly durable so as to noteasily break open. In addition, the concrete bags are often quite heavy,ranging from 40 to 50 pounds or more or less. The scraper flange 13provides a puncturing or tearing device for opening concrete bagswithout the need for a knife or other device. A worker can simply drop aconcrete bag onto the scraper flange 13. The durable shelf 5 can holdthe weight of the bag. The scraper flange 13 will thereby puncture thebag via the impact and weight of the bag. Since the opening is facingthe basin 3 of the wheelbarrow 1, concrete mix drops right into thebasin 3 easily without spilling out onto the ground. The worker can pullthe bag in a horizontal direction against the scraper flange 13, therebywidening and lengthening the hole and allowing the concrete mix to justdrop into the basin 3. The scraper flange 13 therefore allows a workerto quickly tear open bags of concrete mix while minimizing spillage orloss of concrete mix on the ground. As discussed herein, the shelf 5 canbe easily moved between a working position and a storage position, so aworker can move the shelf 5 into the working position over the basin 3to open concrete bags, then move the shelf 5 back into the storageposition at the rear of the basin 3 when done opening concrete bags topermit maximum access to the basin 3 for mixing of the concrete.

FIGS. 38, 39, 40, and 41 show steps in cleaning a concrete broom orbrush with the shelf. Like the screed, brooms used in concrete work arelarge and often difficult to clean, especially wire bristle brooms. Theusual cleaning process is to soak the broom bristles in water, thensmack them on the ground. Not only is this an inefficient cleaningmethod, it also leaves concrete material on the ground of the work site.The shelf 5 permits a worker to scrape off the bristles by brushing themback and forth against the grating of the shelf 5 and/or the scrapingflange 13, as shown in FIGS. 38 and 39 . Instead of smacking the broomagainst the ground, the cleaning of the broom can be finished bystriking the bristles against the shelf 5, as shown in FIGS. 40 and 41 .Any concrete material not removed by the scraping is knocked free andcollected in the basin 3, thereby minimizing the dirtying of the worksite with concrete material.

FIGS. 42, 43, 44, and 45 show views of the upper side of a shelf inaccordance with at least one possible exemplary embodiment. FIGS. 46,47, 48, 49, 50, 51, 52, 53, and 54 show views of the lower side of theshelf shown in FIGS. 42, 43, 44, and 45 . This embodiment of the shelf 5has somewhat different dimensions than the embodiment shown in the otherfigures and omits the scraping flange 13 and retaining bracket 15.
